icmcli analyze concurrency

Report the order that workflows were requested against the order they started.

Synopsis

Compares the order in which workflows were requested with the order in which they started, and writes a report to disk: an order table, a scatter plot, and a gantt chart - plus a manifest explaining how to read them.

Requested order comes from the workflow ID, which is a time-ordered UUIDv7. Workflows created before this version of ICM carry a random ID, so their order cannot be recovered: they are excluded from the report and counted in the manifest.

Scope: the report reads the workflow's start time, which is when ICM accepted the workflow, not when the rate limiter granted it a slot. A workflow that waited a long time for a slot looks the same here as one that did not, so this does not show whether slots were handed out first come, first served, and the gantt bars span accepted-to-finished rather than the copy itself. Exposing the slot grant time (which is what that question needs) is planned in future work.
